Introduction
The UCC24630EVM-636 evaluation module is a 65-W off-line flyback converter providing 19.5 V at 3.33-A
maximum load current, operating from a universal AC input. The module is controlled by the LM5023 ACto-DC Quasi-Resonant Current Mode PWM Controller on the primary side. Secondary-side synchronous
rectification is controlled by the UCC24630 controller. The UCC24630 uses a V/s balancing control
method since the device is not directly connected to the MOSFET drain. The gate output duty cycle is
dependent upon the system line and load conditions, as well as the minimum on time and off times. This
innovative approach results in efficiency, reliability and system cost improvements over a conventional
flyback.

Description
This evaluation module uses the UCC24630 synchronous rectifier controller in a 65-W flyback converter
that exceeds US and European agency standards for efficiency during active load and no-load power
consumption for low-voltage AC-to-DC external power supplies. The input accepts a voltage range of 85
VAC to 265 VAC. The output voltage provides a regulated output voltage of 19.5 VDC at a load current of up
to 3.33 A. The LM5023 uses the transformer auxiliary winding for demagnetization detection to ensure
Critical Conduction Mode (CrCM) operation. The LM5023 features a hiccup mode for over current
protection with an auto restart to reduce the stress on the power components during an overload. A skipcycle mode helps reduce power consumption at light loads for energy conservation applications. The
LM5023 also uses the transformer auxiliary winding for output overvoltage (OVP) protection. If an OVP
fault is detected the LM5023 latches off the power supply.
The UCC24630 uses a V/s balancing control method since the device is not directly connected to the
MOSFET drain. The has a programmable false triggering filter, a frequency detector to automatically
switch to standby mode and pin fault protections.
This User’s Guide provides the schematic, component list, assembly drawing, art work and test set up
necessary to evaluate the UCC24630 in a typical offline flyback converter application.

Circuit Description

www.ti.com
Circuit Description
The input EMI filter is made up of X capacitor C1, common mode inductor L1 and differential inductor L2,
and Y capacitor C19. Excessive surge voltage protection is provided by varistor V1 and input current
protection is provided by fuse F1. Diode bridge D1, input capacitors C2, C3, transformer T1, MOSFET Q3,
LM5023 controller and current sense resistors R11, R11 form the input power stage of the converter.
R3, C4 and D2 make up the primary-side clamp for MOSFET Q3. The clamp prevents the drain voltage
from exceeding its maximum rating.
R5 and depletion mode MOSFET Q2 supply start up bias current to U1 and charge up bias capacitors
C13, C14 and C15. After reaching the VCC(on) threshold the LM5023VSD open-drain output (which is pulled
up to VCC during start up) goes low. This applies a negative gate to source voltage to Q2 turning it off.
This disables the high-voltage startup circuit.
Voltage supervisor device U5 is used to accurately set the turn-on voltage of the power supply. The output
of U5 is high until the voltage on its input exceeds 3 V. This pulls the SS pin on LM5023 low (through Q4
and Q5) and disables startup of the power supply until the input voltage is about 90 VAC . The LM5023 is
thereby enabled and the OUT drive signal starts switching Q3. Energy is stored and then transferred from
the transformer primary to the secondary windings. A bias winding (pins 1 and 2 of T1) delivers energy U1
and maintains the voltage on the VCC pin above its undervoltage lockout (UVLO) value.
Further details on the operation can be found in the LM5023.
UCC24630 controller U2 drives the synchronous rectification (SR) MOSFET Q1.
The control method to determine SR on time is based on the V/s balance principle of primary and
secondary conduction V/s product. This evaluation module (EVM) operates in either Discontinuous
Conduction Mode (DCM) or Transition Mode (TM) and the secondary current always returns to zero in
each cycle. The inductor charge voltage time product is equal to the discharge voltage time product. The
device uses internal ramp emulators to predict the correct SR on time based on voltage and time
information on the VPC and VSC pins. R19 is used to set the blanking time of the VPC rising edge and
determines the minimum primary on-time required to enable the DRV output on each cycle. This prevents
triggering of the SR turn on due to ringing of the MOSFET drain after the SR turn off edge. R17 and R18
program a voltage controlled current source for the internal ramp charging current. This is used to
determine the conduction time for Q1. R15 and R16 determine the primary-side V/s during Q3 on time.
This is used to program a voltage controlled current source for the internal ramp charging current.
Further details on the operation of the can be UCC24630 found in the data sheet.

Efficiency Measurement Procedure
NOTE: The test setup measures the output voltage at the EVM pins and so therefore does not
account for cable losses.
1. Use the test set up shown in Figure 3.
(a) Set the power analyzer to normal mode.
(b) Set the AC source to a constant voltage between 90 VAC and 265 VAC.
(c) Vary the load so that the output current varies from 0 A up to 3.34 A, as measured on DMM A1.
(d) Observe that the output voltage on DMM V1 remains within 5% of the 19.5-V constant voltage
regulation value.
(e) Repeat the test at several line voltages.
6.7
Output Voltage Ripple
An external 10-µF aluminum capacitor in parallel with a 1-µF ceramic noise decoupling capacitor network
should be connected to the output to measure the output ripple and noise. The loop area between the
scope probe tip and ground lead should be minimized for accurate ripple and noise measurements.
6.8
Equipment Shutdown
1. Discharge the output and bulk capacitors.
2. Turn off the AC source.
